I have the very same problem with every page in archive.org.
Some people, also in Trisquel forums, suggest to use it instead of GNUnet or GNU MediaGoblin, but I told them that so far the problems are:
Not all default conversion or publishing formats are free/libre software friendly. It's like they're making free/libre software friendly formats as a "back-up", but aren't making presure so that society uses these free/libre software friendly formats.
The pages for each published work in archive.org require the average (and not tech skilled) user to run non-free software automatically.
